lsperld.fpl always times out

I use an instance of lsperld to serve old-style awstats on one of my servers and I noticed that on 2.2.6 it works fine, but on 3.0 RC2 it times out. I don't know the reason for the hang, because there are no errors I can see in any of the logs. I use exactly the same settings in both. Here is the lsperld setup:

No, you don't need to change configuration for 3.0RC2. Must be something wrong.
Did you upgrade from 2.2.6 to 3.0RC2 on the same server? or try 3.0RC2 on another server? Anything in error.log and stderr.log? Can you try a simple "hello world" perl CGI script?

I upgraded from 2.2.6 to 3.0RC2. A simple hello world script and the awstats.pl both work using CGI daemon, but both hang using lsperld.fpl. I upped the logging to INFO and receive this for the hello world script (awstats.pl is the same):
